Question about ViewSonic VX2433WM 24 inch LCD Monitor
I would get a whining/screeching noise coming from the back of the monitor for about 10 seconds and then the screen would cut out. I thought it might be bad caps and replaced the electrolytics. Firing the monitor back up the same problem occurred. Pulling the covers and shields off and running the monitor bare showed that the noise was coming from the xfmr marked as T501. Is the problem with this xfmr or is something else causing it to make that noise. I can purchase a replacement power board for $30 but would rather try my hand at fixing the board and purchasing a LED monitor.

Blinking on and off is not always a capacitor issue, it is usually caused by faulty transistors at the high output transformers that light the backlights. Crappy board design ! But fixable in most cases.

I had the same problem and called Viewsonic (www.viewsonic.com). Bought mine in July '06 and to my surprise it's still under warranty. The warranty goes for 3 years so even though shipping is my cost, they'll fix or replace it with a same/similar model.

Here is a suggestion:
By looking at the power board you should see the light, and where it is connected to, so diagnose the circut from that point foreward eliminating any potential of damging the board. try any cables or ribbons.
